To a methylene chloride solution (150 ml) of 2-(2-methylpropyl)piperazine hydrochloride (1.50 g) were added 5-chloro-1-phenylsulfonylindole-2-sulfonyl chloride (2.72 g) and triethylamine (2.91 ml). The resulting mixture was stirred at room temperature for 13 hours. Distilled water and methylene chloride were added and the water layer was extracted three times. The organic layers were combined, washed with saturated aqueous NaCl solution, dried over anhydrous sodium sulfate and distilled under reduced pressure to remove the solvent. The residue was subjected to chromatography on a silica gel column (methanol:methylene chloride=1:20), whereby the title compound (2.69 g) was obtained as a brown oil.
